(I am disabled and have a service dog that accompanies me everywhere, including my job. I typically run a register, and he will either sit or lay beside me on the rubber mat behind the register. I typically don’t talk about my disabilities with strangers, since some people can be rather mean.)

Customer: “Oh, a service dog! Are you training it?”

Me:*ringing up customer’s items* “No. He’s mine.”

Customer: “But you don’t look disabled.”

(I just smile and continue their transaction.)

Customer: “Oh! Do you have seizures?”

Me: “Something like that.”

Customer: “Diabetes?”

Me: “Something like that.”

Customer: “PTSD?”

Me: “Something like that.”

Customer: “Well! I wasn’t trying to be nosy. Hmph!”

Me: “Sorry about that. Your total will be [total].”

(The customer pays and takes his bags, starts heading for the door before turning back to me.)
